Application filed nuary 18,1904:- Serial No. 189,591.

Tr all TIJIL/OHZ/ it may concern Be it known that we, Trroaus BENJAuINLumen, manager, residing at 10 Lemna road, Leytonstone, in the county ofEssex, and Tnonas LAKE, engineer, residing at 2801'- chard Place,Blackwall, in the county of Mid dlesex, England, subjects of the Kingo'fGreat Britain, have invented a certain new and useful Improved Anvil forMaking Tanks, Cisterns, Boxes, or the Like, of which the 'following is aspecification, reference being had to the drawings hereunto annexed andto the letters marked thereon.

The invention relates to improvements in means employed in themanufacture of metal tanks, cisterns, boxes, or the like.

According to a former invention of one of us -namely, the said ThomasBenjamin Leecln the ordinary method of constructing metal tanks,cisterns, or the like by riveting the plates together at the angles wasdispensed with and in lieu thereofsaid plates were joined at the anglesby means of long clips of poculiar construction which embraced thereturned or flanged edges of the plates. The side joints thus formedwere closed by means of a bar-like anvil and a tilt-hammer, but thejoints at the top and bottom of the tank were closed by hand, rivetsbeing afterward inserted at the corners and the tank dipped in thegalvanizing-bath.

Now the primary object of the present invention is to provide meanswhereby the closing of the joints of the top and bottom of the tank mayalso be accomplished by the aid of a tilt-hannner or the like, thuseffecting a considerable economy in time and labor and improving thefinish of the tank.

In the accompanying drawings, Figure 1 is a side elevation, partly insection, of an anvil constructed according to the present invention witha tank in position thereon and a coacting filt-hannner. tion of partstaken on the line 1 1 of Fig. 1. Fig. 3 is a side elevation of the topof the anvil. Fig. El is a plan thereof. Fig. 5 is a front elevation ofthe top of the anvil. Fig. 6 is a sectional view of parts, showing ajoint at an angle of a tank resting upon the anvil Fig. 2 is a verticalsec- 3 prior to the closing of the seam. Fig. 7 is a similar view, butshowing the parts after the closing of the joint with the hammer inaction. Fig. 8 is a similar view to Fig. 1, but illustrating a modiliedmethod of mounting the anvil. Fig. 9 is a front elevation thereof,partly in section; and Fig. 14) is a sectional elevation of a modiliedform of pillar, showing a tank in position.

In the several figures like parts are indicated by similar letters ofreference, and Figs. 3 to T are drawn to an increased scale with respectto the other ligures of the drawings.

Referring to Figs. I to T, represents the floor upon which the workmanstands. I) represents a pillar or standard which supports the anvil. 7;represents the anvil. represents the hammer. w represents the head ofthe hammer, which is shaped to coact with the anvil. /2 represents atank in position upon the anvil for the closing of one of the bottomjoints by the hammer, and 1! represents a joint at one of the angles.

The pillar 7; is sunk below the floor u in order to bring the anvil b toa convenient height for the workman, and at its upper end it is formedwith a crank or offset 7/, the objectof which is hereinafter explained,and which at its outer extremity is provided with a vertical hole orbearing 7).

1n the hole or bearing b is revolubly mounted the reduced end of a shortspindle or stud 7), which takes a bearing upon the crank or offset 7/and is fastened in position by a nut I), screwing upon the threadedlower end of the spindle I) and a washer If, which takesa bearingagainst the under side of the crank or off set b.

Upon the upper end of the spindle Wis iixed the anvil l), which isformed with a tapered hole or socket therein which receives thecorrespondingly-tapered upper end of the spindle 7), upon which theanvil is driven and securely held by friction.

The anvil consists of a bar, square in crosssection, and it is mountedupon the spindle Z) in such manner that a line drawn verticallytherethrough would intersect two of its angles, the upper one of saidangles constituting the surface upon which the work is performed, whilethe anvil is of a length considerably less than that of a joint, and itis unequally mounted upon the spindle Z in order to facilitate theinsertion thereof into the tank (Z by the manhole (Z thereof and for thepurpose hereinafter described.

By reason of its short length and unequal mounting the anvil Z isincapable of supporting a joint for its entire length, as will be seenon reference to Fig. 2, and it is therefore necessary to turn the anvilthrough an arc of one hundred and eighty degrees, as shown by the dottedlines in Fig. 4, and in order to complete the joint and to insure itsbeing turned into correct position in either direction a horizontal studor projection Z is fixed upon the spindle Z and coacting stops Z areprovided upon the cranked upper end 6 of the post or standard Z).

It will be understood upon reference to Fig. 1 that the object offorming the pillar b with the crank or offset Z1 is to bring the anvilZ) into the required central position with relation to the tanknotwithstanding that the manhole (Z through which the pillar Z isintroduced, necessarily occupies an eccentric position when the tank (Zis resting upon the anvil in the required manner.

The mechanism for actuating the tilt-hammer c is of a very ordinarycharacter; but a short reference to the principal parts thereof mayassist persons unskilled in the use of such machines to betterunderstand the same. The arm of the hammer is pivotally mounted at 0beyond which point it is acted upon by tappets 0 carried by a wheel 0*,by which it is intermittently raised and released, while the suddendescent of the hammer is assisted by a spring 0. The wheel 0* isconstantly driven through suitable intermediate gearing from a pulley a,driven by a belt 0 and in order that said belt may be tightened so as toset the machine in motion at the will of the workman a lever 0 pivotallymounted at c", is at its upper end provided with a jockeyroller 0adapted to impinge upon the belt 0 and at its lower end is provided witha cam or incline adapted to be acted upon by a stud or roller c carriedby a pedal-lever c to bring the jockey-roller into action, a spring 0being employed to impart the return movement to the lever 0 The methodof constructing a tank, aided by the means hereinbefore described, is asfollows: The four sides (Z of the tank are first loosely jointedtogether by clips (Z. The top (Z is then similarly connected to thesides (Z, after which the joints (Z, connecting the side plates (Z, areclosed by means of a tilt-hammer and an ordinary anvil consisting of along fixed horizontal bar. The tank thus partly made is then removed tothe anvil Z, constructed according to the present invention, which isinserted through the open bottom of the tank, and the four joints (Z atthe angles connecting the top (Z with the sides (Zare closed by thetilt-hammer 0. One half of each joint is first closed with the anvil Z)in one position. The tank is then raised and said anvil is turned andthe tank adjusted to the required position upon the anvil, and the otherhalf of each joint (Z is similarly closed. The tank (Z is now removedfrom the anvil Z), and the bottom (1* thereof is loosely jointed to thesides (Z by clips (Z, as hereinbefore described with respect to theother joints. and the tank is passed over the anvil by way of themanhole (Z when the four joints (Z, connecting the bottom (Z with thesides (Z, are closed in a similar manner to that described with respectto the top (Z The whole of the joints having been closed in the mannerabove described the tank is removed from the anvil, a conical rivet isinserted at each of the eight corners, and the tank is subsequentlyimmersed in the galvanizing-bath in the usual way.

In the example given at Figs. 8 and 9 the anvil 6 instead of beingpivotally mounted upon the crank or offset 5' of the pillar Z isconstructed to slide endwise with relation to the stud b in order toshift the same from one part of a joint (Z to the other. For thispurpose the upper end of the stud Z is formed with a V-shaped saddle 6,adapted to embrace the lower angle of the anvil b and providedlongitudinally thereof with hook-like flanges or projections 6 whichengage corresponding undercut grooves or Ways Z2 formed in the anvilZ)", while the anvil is provided with projections Z), by the aid ofwhich it may be shifted upon the saddle Z), and which also act as stopsto limit its extreme movement in either direction.

In the example given at Fig. 10 a modified form of pillar is shown, inwhich the pillar Z instead of being formed with a cranked offset Z) isitself bent or curved in order to bring its upper end into the requiredcentral position, and the stud or spindle b is formed with an annulargroove 5 which is engaged by a set-screw Z in order to hold the studagainst vertical movement while permitting it to rotate.

It will be obvious that the anvil b may be usefully employed for closingjoints of other descriptions than the clip-joints hereinbefore describedor for riveting in similar situations. It will also be understood thatthe details of construction ofthe device may be otherwise considerablymodified without departing from the spirit of the invention.

By the means hereinbefore described the top and bottom joints of a tankor the like may be closed with the same efficiency as the side joints,while at the same time said operation is facilitated and cheapened.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, we declarethat what we claim is 1. In means employed in the manufacture of metaltanks, cisterns, boxes, or the like, a vertical pillar adapted to passthrough a hole in the tank and having a horizontal crank at its upperend, a vertical stud at the end of said crank and an anvil having aninverted- V-shaped upper edge supported by said stud substantially asherein shown and described and for the purpose stated.

2. In means employed in the manufacture of metal tanks, cisterns, boxes,or the like, a vertical pillar adapted to pass through aholc in the tankand having a horizontal crank at its upper end, a vertical studrevolubly mounted at the end of said crank and an anvil having aninverted-V-shaped upper edge supported by said stud substantially asherein shown and described and for the purpose stated.

3. In means employed in the manufacture of metal tanks, cisterns, boxes,or the like, a vertical pillar adapted to pass through a hole in thetank and cranked to bring its upper end into the required centralposition with relation to the tank and an adjustable anvil having aninverted-V-shaped upper edge supported by the upper end of said pillarsubstantially as herein shown and described and for the purpose stated.
